Spinners are the only way to go! I bought a carry on and a full sizer with 4 wheels each and it's so easy to get around everywhere, airports, gangways, sidewalks, and any other place us travelers love to go. And thats even when the luggage weights in at an even 50 lbs. Ross Dress For Less has lots of selection for cheap, so you can always get one and try it out on a world cruise to make sure you like it.
